The invention relates to the technical field of detecting devices and in particular to a positive osmotic membrane performance testing device. The positive osmotic membrane performance testing devicecomprises a base. One side of the upper end of the base is vertically welded with a straight plate, and the other side of the upper end of the base is vertically welded with a supporting plate. The middle of one side, adjacent to the supporting plate, of a motor box is provided with a circular hole. The middle of the upper end of one side of the straight plate is fixedly provided with a shaft base. The shaft base is internally and rotatably provided with a threaded rod. The threaded rod is in threaded connection with a first thread sleeve and a second thread sleeve. The first thread sleeve andthe second thread sleeve are provided with limiting mechanisms. The bottom of a connecting rod is connected with a U-type frame. The middle of the upper end of the U-type frame is provided with a clamping mechanism. One side of the upper end of the U-type frame is provided with a fixing mechanism. The lower end of the outer side of the straight plate is provided with a connecting mechanism. The positive osmotic membrane performance testing device is stable in structure, convenient for testing performance of a positive osmotic membrane, and good in detection effect.
Description
technical field [0001] The invention relates to the technical field of detection devices, in particular to a forward osmosis membrane performance testing device and a testing method thereof. Background technique [0002] Forward osmosis is a natural phenomenon, but it is also a concentration-driven new membrane separation technology developed in recent years. It relies on the osmotic pressure difference on both sides of the selective permeation membrane as the driving force to spontaneously realize the membrane separation process of water transfer. , is one of the hotspots in the field of membrane separation research in the world. [0003] The existing forward osmosis membrane detection devices on the market have poor structural stability, poor fixation and clamping effects on the forward osmosis membrane, resulting in large errors in detection results, cumbersome operations, and unrepresentative detection structures. Not conducive to promotion. Contents of the invention ...
